How is the signal to noise ratio of the unit itself (if the input is super clean...is there any added hiss from the electronics from this unit)?

I don't know the exact DB range but this unit has exceptionally quite preamps. I have used it many times to record direct outs from a board during a live performance and have always been happy with the sound quality! Be sure to set the unit to 24bit depth recording in the option menu.

I haven't compared to professional recording quality, so not sure, but I can't detect any hiss from the electronics of the Zoom. This said, if I were buying another recorder, I think I prefer Tascam quality in general.

I had no hiss, but check inside the bottom of the speaker I did have a piece of plastic wrap packed inside that caused a noise. But once I removed it, it was fine.

This sub woofer is powered, the input is line type voltage 3v, it does not require a large gauge wire. The signal coax that comes with it is sufficient. As for empirical data, my system with a Sony 7.2 head, optical connection, various side, front, and back speakers, and this sub woofer makes no discernible sound noise or hum when "silent" even when turned up very ~%75 of max loud. Often normally unheard quiet sounds from movie, or game sound tracks will be mistaken for "far away sounds" outside. The quality is excellent. Once when we were playing a game, it sounded like there was a faint scratching coming from outside. It took us about 5 minutes to realize it was actually a subtle part of the soundscape.

Your source is doing that. Try plugging it in a different device. Hiss gone, guaranteed. (Late answer, but might help future inquirers).

Yes I have the same hissing sound on my unit too. Not too excited about it either. I am from Canada, and shipping it back and forth to the USA will be too much of a hassle and too expensive to do, so I'll just keep it as is. :-(

Audio had a slight buzz that I believe same from the low quality switch mode pier supply. I was going to experiment with a battery yo confirm, but as of yet have not tad time. My guess is it would be wise to go with an aftermarket linear power supply to have the cleanest audio. The I purchased did come with antenna, the rubber duckies type.

At low volumes it is not very noticable... but if you crank it up then turn off the source of the audio (like turning off your tv) leaving the sound bar on...then the hum is bad.

All of what has already been said, AND, the headphone link is very noisy. Mine is anyway. Buzzes...hums... Same with two different inputs, two different power sources, no matter where it is placed. It's not an enviromentally induced noise...it's the converter.

the reason for the hiss is the high gain amplifier in the original variant of this model. when you sent your amp into their factory, they replaced it with a unit of slightly lower power [not enough for you to notice, but enough that it probably effects the actual specs slightly regarding RMS/Wattage and all that] - therefore less hiss when you crank the speakers and have no sound playing. When I had my set [amazing speakers by the way] - the hiss was only noticable if a) there was nothing playing and b) you crank it far past what I consider reasonable close range listening levels. these things go LOUD far before you hit anywhere near 9 on the dial. still, some will prefer the newer variant. the reason for the hiss is the high gain amplifier in the original variant of this model. when you sent your amp into their factory, they replaced it with a unit of slightly lower power [not enough for you to notice, but enough that it probably effects the actual specs slightly regarding RMS/Wattage and all that] - therefore less hiss when you crank the speakers and have no sound playing.

As Jeffrey...Yes, I have the same hissing sound on my unit too... I am from Canada, and I cannot shipping it back to the USA since It will be too expensive to do so, so I'll just keep it as is.

I noticed it too. When the device is connected via the instrument connection the floating ground will cancel any noise. One must remember, this isn't a professional piece of equipment with layers and layers of MOSFETS, JFETS AND TRANSISTORS To switch on and of the signal. So, even though there is no signal, it's amplifying the hum from the AC transformer as well. In common terms, it needs to be connected to a device to cancel the noise. Even in the ground, or lift phase.

Honestly I'd go with the Rolls solid state pre-amp filter and not the passive like I have - I'm going to have to call Rolls and to see what's the best device to boost the input signal into the passive filter - I'm getting excellent sound but I want more volume when using the G5 - for most people it would be more than loud enough - it's really a simple fix of having a good pre-amp - I see what your doing - all I can say is I'm not having your problem with my set up - you need to make sure your signal is clean

Mine has zero noise. Try turning down the gain and put in on the clean channel. It should be silent (unless you have the volume way up). You may get some negligible noise on the crunch or overdrive especially if the gain is turned up. Read through the manual. Amazon should return if you have issues.

I don't experience a hiss, but it's common if attaching speakers to internal audio cards due to electrical interference. Some computers are designed to handle this better. Similar to Rob, my MBP does that when attached to an external monitor. My PC has no problem. If you keep experiencing hissing problems and it bothers you, consider a USB sound card.

I too get a low level interference noise from my PC. Ive tried different cables and mixers, some are better than others, but I cannot make it disappear completely because all of my cables ten to "run together" around my desk. That said shielding the signal wires from stray RF is your only option, OR turn them up really LOUD. Just kidding.

We have had no issues with the unit as of now. If there is background noise, it is very low. But I should qualify that we are using it to send our low end noise to sub-woofers mounted under our seats and it would take quite a bit of noise for us to detect it.Rick Blair

I discovered that same hiss when my TV was connected to a DTV converter box, equipped with its own universal remote. I was able to eliminate the hiss by lowering the volume on the TV's remote. I use the converter boxes remote to power on and off the tv as well as change channels and raising and lowering the volume. Note that everytime the tv suffers a power interuption by either being disconnected or power outage, I have to again lower the tv volume (and raise the volume using the converter boxes remote
